The normal cholinesterase activity in brain tissue was measured in 15 mammalian and 44 avian species using the Ellman method. Enzyme activity exhibited considerable interspecies variability. In mammals, the enzyme activities ranged from approximately 2 to 10 micromole/min/g of wet tissue. With the exception of the carnivores (dog, fox, coyote), no consistency of the enzyme activity could be identified in related mammalian species. The range of interspecies differences associated with avian… CONTINUE READING
